iOS 7.1 beta for iPhone, iPad released to developers, here’s the changelog

Apple on Monday released its latest “magical’ update for iPhone, iPad, and iPod touch. The company released the first beta of iOS 7.1 (build 11D5099e) to developers. Registered developers can now download iOS 7.1 beta from the developer center for their iOS 7 compatible devices such the iPhone 5, iPhone 5c, iPhone 5s, 4S, 4. As you would expect the update can also be downloaded to iPads including the new iPad Air, iPad 2, 3.

According to iPhone hacker iH8sn0w, theupdate will expire on Monday, January 13, 2014. But it’s unknown how many beta Apple will release until the update hit public.

CFNetworkFixed in iOS 7.1 betaPreviously, if the server-side closed an HTTP request with TCP FIN without sending any bytes of HTTP header or HTTP body, NSURLConnection would synthesize an empty HTTP/1.1 200 OK response. This is now fixed, and the request will result in an error instead of a successful load with a synthesized response.

NotesA new compatibility behavior has been added to address an issue where some web servers would send the wrong Content-Length value for “Content-Encoding: gzip” content. Previously, NSURLConnection and NSURLSession would send a “network connection was lost” / NSURLErrorNetworkConnectionLost (-1005) error in this situation.

The compatibility behavior applies only if the Content-Length value exactly matches the expanded gzip’d content. It won’t apply for “off by 1” or similar miscounting.

Core TextFixed in iOS 7.1 betaPreviously, text drawn with CTFrameDraw did not correctly place lines to account for the paragraphSpacing attribute of NSParagraphStyle. This has been addressed in iOS 7.1 beta.

Crash LogsKnown IssueCrash logs will not appear in Diagnostics & Usage Data in Settings. The logs will still be available when synced off the device.

GLKitFixed in iOS 7.1 betaIf loaded with GLKTextureLoader, pngcrush images that have alpha were not unpremultiplied.

High Precision TimersFixed in iOS 7.1 betaWhen sleeping or waiting for extremely precise time intervals, timers were delayed by up to 1 millisecond.

iTunesKnown IssueLoading an iTunes Match library (or your purchased music history) may take much longer than expected, especially on larger libraries. If your library does not sync right away, please wait 30 minutes and try to access it again.

Multipeer ConnectivityFixed in iOS 7.1 betaThe MCSessioninitWithPeer: method has now been implemented properly.
